FIELD OF INVENTION

Embodiments of the present disclosure relate to data acquisition from internet, and more particularly to a system and method to acquire data from a deep web.

With linear growth in the technology, internet has become a source for immense quantities of data, which is used for various purposes by different organizations. One such purpose includes detecting a threat for the organization such as malicious activity or hacking. In general, the data in the internet is classified between surface web and deep web, which includes dark web. It is well known today, that most of the illegal activities or planning for a malicious activity take place in the deep web. Therefore, acquisition and analysis of data from the deep web has become important for the organizations to identify potential threats.

Conventional systems utilized by the organizations for detecting threats are capable of acquiring data from the surface web, which includes data that is accessible by the well-known search engines. However, the conventional systems are unable to acquire data from the deep web as acquisition of data from the deep web requires advanced web crawlers capable of accessing the deep web. Furthermore, additional security protocols are required to be maintained by the system for maintaining anonymity.

In comparison to the conventional systems, newer systems are capable of acquiring data from the deep web as the newer systems employ advanced crawlers and security protocols to acquire the data from the deep web. However, the newer systems are susceptible to breach upon accessing the deep web as the newer systems employ a single layer of anonymity, which if breached enables a hacker to hack the system. Moreover, the newer systems have limited data acquisition capabilities as the newer systems employ one computing device for acquiring data from the deep web.

Hence, there is a need for an improved system and method to acquire data from the deep web to address the aforementioned issues.
